To all fui/wm t may concern.'

Be it known that I, BYnRs W. KABEL, a

.citizen of the United States, residing at Baltimore, inv the State of Maryland, have invented certain new and useful Improvements in Composite Car Framing; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

The invention relates to railway cars, and more particularly to plate members adapted to be used in the construction of gone dola and cars of like character.

The principal object of my invention, broadly stated, is to provide plate-like members which may be produced by an inexpensive process and which are suitable for use in constructing the side walls of gondola cars.

lAnother object of the invention is to provide plate members comprising expanded metal plates having solid marginal edges, the expanded metal being covered by a composite filler whereby the metal is protected from the elements and rendered sufficiently rigid to aord efficient side walls for a car construction.

There are other objects of the invention as will hereinafter more fully appear from the detailed description of the single embodiment thereof which has been chosen to illustrate the invention.

ln the drawings,-

Figure l is a fragmentary side elevation of a portion of a gondola car showing the invention applied thereto.

Figure 2 is a transverse sectional view Showing the manner in which the plates are connected to the load carrying frame of the car.

Figure 3 is a perspective view of one of the plates.

The numeral l designates a railway car having the usual form of angle iron framework 2 to which in general practice is ap plied the sheet metal siding in order to complete the side walls of the car. rlhe numeral 3 designates a plate embodying my invention. rlhe plate is preferably formed from relatively thin metal having the interior portion 4 thereof expanded or perforated as is common in expanded metal.

The vmarginal edges 5 ofthe plates are preferably reinforced by overlapping two thicknesses of the plate, as clearly shown at 6 in Fig. 2. These marginal edges are punched as at 7 to provide rivet receiving openings for the reception of rivets 7 by which the' plates are attached to the car framework 2. The intermediate or eX- panded metal portion of the plate is coated or covered with a composite filler 8. This composite filler may comprise concrete. It is, however, preferably formed of a mixture of cellulose, cement and plaster of Paris. Such a compound is inexpensive, simple to apply land has the requisite strength and rigidity, and forms a surface which is practically impervious to the action of acids. The surface is also of suiiicient hardness to prevent rapid wear`by the lading of the car. It will be understood, however, that while I have particularly described one plastic compound, l do notflimit myself thereto, since many other compounds may be advantageously appliedor used in co'mbination with the expanded metal plate.

1. In a railway car, the combination with a metallic load carrying frame, of wall members, said wall members including a plurality of plate like elements each of which comprises a single metallic frame section and a composite ller, said composite ller terminating short of the surrounding marginal edges of said metallic frame section.

2. In a railway car, the combination with a metallic load carrying frame, of plate members secured thereto, said members comprising plates'of expanded metal having applied thereto in spaced relation to the marginal edges thereof a composite filler.

3. In a railway car, the combination with a load carrying frame, of wall members therefor, said wall members comprising a plurality of plates having their. adjacent edges overlapped, the central portions only `of said plates having applied thereto a composite filler.

4. ln a railway car, the combination with a load carrying frame, of wall members therefor, said members comprising a pluralityY of overlapping plates, the central portions of which are formed from expanded metal covered with a composite ller, the marginal edges of said plates being perforated, and fastening means eX` tending through the perforations in two adjacent plates.

5. An article of manufacture comprising a plate, the central lportion of which .is formedy of expanded metalcovered with a compositefiller7 tlie margins of said plate being integrally connected to said central portion and being provided with openings adapted to receive means for securing said plate to a support.

- 6. An article of manufacture comprising an integral `metal plate having its central portion'formed-of expanded metal, aV composite filler covering` said central portion, themarginal edges of said plate beingbent vto said frame with their edges overlapping adjacent uprights, said plates constituting load retaining Walls, each of said plates comprising an integral metal plate having ,its central portion. formed of expanded metal, means for reinforcing the edges of said plates, and means passingthrougli said edges for connecting theplates to thecar frame. e i
